I'm using a geriatric G4, and want to upgrade to the new 27" i7 quad core. My knowledge of many HW matters is badly out of date. Some questions follow. Your expert advice will be much appreciated.
1) I do not do graphics heavy application work, and watch a streaming film once in a while. Is there any point to getting 2 mg of video memory rather than the 1 mg in the standard config.?
2) I need a new wireless router to replace my ancient d-link 802.11g, which drops its connection to my wife's core two duo iMac 24" with great frequency. We have to unplug/reset the DSL modem to re-establish a connection. Queston: Airport Extreme or Linksys or some other brand? I want a dual frequency router with setup that doesn't require a PhD in technobabble, though I don't mind reading directions.
3) Can you suggest sources for an 8 mg RAM upgrade? Apple seems to gouge on price.
Thanks very much for your help.
